⭐ Expert Tips for Success
- Drain Your Tuna Properly: Whether using oil-packed or water-packed tuna, draining it thoroughly is key. Excess moisture leads to a watery salad.
- Use Quality Olives: Kalamata olives are highly recommended for their distinct, rich flavor, but high-quality Nicoise or Castelvetrano olives also work beautifully.
- Rest for Flavor: If you have time, let the prepared salad chill in the fridge for 15-20 minutes. This allows the lemon and oregano flavors to meld beautifully.
- Red Onion Soak: If you find raw red onion too strong, chop it and soak it in cold water for 5 minutes. Drain it before adding it to the salad to temper the sharp flavor.
Variations & Substitutions
This Mediterranean Tuna Salad is wonderfully flexible. Feel free to customize it based on what you have in your pantry!
- Make it Keto/Low Carb: Serve this salad in lettuce cups, stuffed into bell peppers, or over a bed of spinach instead of pita or crackers.
- Add Crunch: Toss in some chopped cucumber, toasted pine nuts, or crunchy sunflower seeds.
- Different Protein: Swap the tuna for canned salmon or even shredded rotisserie chicken for a similar effect.
- Dairy-Free Option: If you need to skip the feta, add sun-dried tomatoes (packed in oil) or capers for that essential salty, bright kick.
Storage & Make-Ahead Tips
This salad is perfect for meal prepping!
Store the Mediterranean Tuna Salad in an airtight container in the refrigerator for up to 3 to 4 days. Because it contains no mayonnaise, it holds up exceptionally well.
We do not recommend freezing tuna salad, as the texture of the vegetables and cheese will become mushy upon thawing.
